According to TechFlow, the Celo Foundation announced the successful launch of the Layer-2 testnet Dango, which is built on Optimism’s OP Stack and uses EigenDA to maintain low transaction fees.

This launch retains all historical data of the Alfajores testnet. The core features include: bridging WETH and ERC-20 tokens, reducing block time to 2 seconds, supporting multiple ERC-20 tokens as gas currencies, sending funds through SocialConnect, and keeping gas fees low. It is expected that the Celo Layer-2 mainnet will be officially launched in early winter 2024.
